Her mother, Heidi, captured the moment a massive tornado was moving behind them in this pre-prom photo:

Marintzer said when they first spotted the tornado, it was a small funnel cloud which quickly developed into the bigger tornado.

At an estimated distance of about 2.5 to 3 miles from their home, Marintzer realized the tornado never posed a danger to the family and once it weakened, Heidi took her phone out and snapped the shot of the teens with the tornado in the background, as seen in the photo above.

Ali and Charlie also took the time to admire the powerful tornado after creating the epic photo.

The prom was not canceled, but it was delayed by about 45 minutes to make sure everyone was safe, Marintzer said.
